JOHN MAJOR BISHOP, OF HUNTSVILLE, ALABAMA.

'BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 563,441, dated July 7,1896.

Application filed September 25, 1895. Serial No. 563,5 '71. (No model.)

To all whom it may concern:

Be it known that I, J OHN MAJOR BISHOP, a citizen of the United States,residing at Huntsville,in the county of Madison and State of Alabama,have invented certain new and useful Improvements in Baling-Presses; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

The special object of the invention is to make the toggles ofbaling-presses work more smoothly and with less frictional wear.

Figure l of the drawings is a perspective view showing the inventionapplied. Fig. 2 shows a number of detail views, and Fig. 3 a horizontalsection.

In the drawings, A represents the press;

B, the follower; O D, the toggle-arms, and E the lever by which thetoggle is operated.

F is a lever-brace supported on an upright G, and H a pin which holdsthe lever-arm D. c d are pins on which the toggle-arms turn, and d ahole through which passes the pin H.

c d are the toggle-arm-contacting heads. The ends of the arms 0 D arerounded and faced with metal which will take up wear and be readilyreplaceable. The pin cl is allowed some play, so that when the heads areapproaching alinement the strain will be thrown upon the head 0', whosepin 0 has a corresponding play. This transfers the strain to thefollower-socket b and the press operates with much less frictional wear.At the middle of the curve of the heads 0 d are formed, respectively,the concavity c and projection d the latter to work in the former, sothat the toggle-arms may more exactly aline and with less friction.

What I claim. as new, and desire to protect by Letters Patent, is

In the operative mechanism of balingpresses, two toggle-arms having playon their joint-pins and provided with rounded convex heads, one headhaving a concavity and the other a convexity fitting therein, at thepoint of greatest convexity, whereby a maximum of power is obtained witha minimum of strain on the joint-pins, while the mechanism works with acontinuously smooth action, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN MAJOR BISHOP. -Witnesses:
